3M 7000042703 Hook Saver Disc Pad Protector 6 Inches

Product Description

The 3M 7000042703 is a hook saver disc pad protector designed to extend the service life of Hookit disc pads used in clean sanding applications. It mounts between the disc pad and the abrasive disc, absorbing wear on the hook surface so the pad itself is not consumed during normal sanding operations. Measuring 6 inches in diameter with 52 through-holes, the hook saver aligns precisely with the hole pattern of compatible Hookit clean sanding disc pads to maintain proper dust extraction performance. Abrasive and finishing technicians install this part as a low-cost consumable replacement for a more expensive pad assembly.

This hook saver is intended for use in automotive refinishing, woodworking, and general surface preparation environments where random orbital or hook-and-loop sanding systems are in service. It is used on disc pad part number 20356 Hookit Clean Sanding Disc Pad. The 52-hole pattern on the hook saver matches the 52-hole layout on that pad, ensuring unobstructed airflow and dust collection through the backup pad and sander during operation.

Key Features

• 6-inch diameter fits standard Hookit clean sanding disc pad configurations
• 52-hole pattern aligns with the PN20356 Hookit Clean Sanding Disc Pad for uninterrupted dust extraction
• Consumed in service as an inexpensive sacrificial layer, protecting the more costly disc pad hooks
• Designed for use on PN20356 backup pad (BUP)
• Sold individually (each unit of measure)

Compatibility

Designed for use with the PN20356 Hookit Clean Sanding Disc Pad. The 52-hole pattern of this hook saver corresponds directly to the 52-hole layout of that disc pad.

Installation Notes

Power down and disconnect the sander from its air supply or electrical source before servicing the pad assembly. Position the hook saver against the hook surface of the disc pad prior to attaching the abrasive disc, ensuring the hole patterns are aligned for proper dust extraction. Replace the hook saver when wear is visible on its surface rather than allowing wear to transfer to the disc pad hooks. No specialized tools are required for installation or replacement.
